Do Java Lambda Expressions Utilize “Hidden” or Local Package Imports?

Question

This question is about the apparent \"hidden\" or local imports of Java packages that lambda expressions seem to employ.

The following sample code compiles and runs

Answer 1

I think the point you're trying to illustrate can be simplified like this:

This lambda requires an import

Paths.get("path").forEach((Path filePath) -> {});

This lambda does not require an import

Paths.get("path").forEach((filePath) -> {});

Since Path.forEach(...) takes a Consumer I presume the latter case is creating a new type on-the-fly of ? super Path, and thus you don't need an import since it's a new type (like a generic type at runtime)
